In their (desperate) efforts to prevent spam, my provider blocks tcp/25 outbound. It makes no difference whether I have a PTR or not, I can't connect to any mail servers. And AFAIK that's fairly common, at least in the US. My provider doesn't support v6 yet, so I don't know whether this policy will extend there; I have every expectation that it will.
